We only have information that is released to the media and that includes shows that are greenlit for CBSAA. Other shows for CBS and CW though always have the possibility to get put out to pasture on CBSAA instead of the "Friday-night-death-slot" on CBS or CW linear networks.CBS needs a better marketing game but if it's not ready, why announce something? The attention span of consumers now is so short that they could announce now, and it's forgotten by next week.
This is what I mean by holding on to their cards.
One new show for CBS in the sci-fi thriller genre coming in Summer 2017
CBS gave a straight-to-series order to a suspense thriller that the network has slotted for broadcast in summer 2017. The project is “Salvation,” about an asteroid on a collision course with planet Earth.
Executive producers are Liz Kruger and Craig Shapiro, who wrote the script based on a story by Matt Wheeler; Alex Kurtzman; Heather Kadin; and Peter Lenkov.
http://www.tvweek.com/tvbizwire/2016/10/cbs-orders-event-series/The network ordered 13 one-hour episodes of the project from Alex Kurtzman’s Secret Hideout and CBS Television Studios.
So if Salvation does terribly on CBS there is new rating metrics.
In advertising circles, the Live-plus-7-day (L7) [C7] rating period is becoming increasingly irrelevant as viewers watch content on a variety of devices at different times.
the window for regularly reported on-demand and DVR data now will extend to 35 days after the original airdate.
Most media buyers are quick to note that the difference between C3 and C7 ratings are minimal. The notion of a C35 rating, something that likely will be floated in future upfront markets,

So while 2017 is a year of original shows it is possible that in the future CBS will move underperforming shows to CBSAA to make room on their linear channel for new shows. Kind of "filler" between original shows for CBSAA.
Especially when CBS Television Studios is the producer in the first place they already own the show. Also another thought about "filler" is as soon as a show finishes it's first run on CBS linear channel will it end up on CBSAA or not until the DVD product release cycle from CBS Home video. I don't say Blu-ray since so many of their shows are DVD-only since the Blu-ray product didn't sell well. Take CSI for example only season 1 and season 9 got a US market release in Blu-ray. All other seasons were DVD-only. If you want HD you have to goto iTunes, Microsoft TV & Movies, Google Play, or now currently Hulu has CSI streaming.
